Trying to fix PS3 brick using PSP jig help?

I'm getting the 5 beeps of death when going back from CEX to DEX. I'm using the psp jig but its only getting me so far.

Using my psp i can get this far:

On the PS3:

2. Switch off ps3 from power cord
3. Put the USB Dongle with service mode payload in the right usb port
4. Put power cord in the console
5. Press power button followed quickly with eject button, the console should boot, and then reboot. (if the beeps continue it's normal)
6. Remove service dongle
7. Put the USB Pen with the 2 files inside in the right usb port
8. Power on the PS3. If all went well you shall see the ps3 reading stuff in the usb pen, and the hard drive of ps3 working, wait for the console to power off

On step 8 i'm still getting the 5 beeps even though the jig has worked. What am i doing wrong? I've put the files onto a usb stick but the ps3 doesn't seem to be reading it. Its annoying me now
